Water Quality Legend

Current Status

Grey means water quality information for the beach is too old (more than 7 days old) to be considered current, or that info is unavailable, or unreliable.

Historical Status

When swimming season is over or when a beach's water quality data has not been updated frequently enough (weekly) it goes into historical status. This means that rather than displaying current data it displays the beach's average water quality for that year.

Green means the beach passed water quality tests 95% of the time or more.

Yellow means the beach passed water quality tests 60-95% of the time.

Red means the beach failed water quality tests 40% of the time or more.

Special Status

We may manually set the status for a specific beach if we have concerns about the sampling protocol, if there is an emergency, if monitoring practices don't exist or have recently changed, or other reasons that render this site "special."

Green means the beach has historically excellent or pristine water quality, but there is no current data.

Red means the water at the site has water quality issues or there is an emergency.

Grey means there is no current water quality information, the beach is under construction, there has been an event that has rendered water quality information unreliable or unavailable.

See the beach description for more information regarding their special status.

SOURCE INFORMATION

Through its Beach Monitoring Program, the South Carolina Department of Health and Environmental Control (DHEC) monitors the level of enterococcus bacteria at 122 sites along South Carolina’s coast. Testing is conducted during the beach season from May 15th to October 15th. Monitoring levels of enterococcus bacteria is the best way to determine whether disease-causing pathogens may be present in ocean water.

DHEC monitors 27 sites at our local beaches (Isle of Palms, Sullivan’s Island, Folly Beach, Kiawah, and Seabrook). Monitoring sites are located near public access points to ensure the public’s safety. DHEC monitors our local beaches twice a month. When sample results are published on the Program’s website, Charleston Waterkeeper updates Swim Guide.

A “Green” site = test result of 103 MPN/100 mL or lower OR a test result between 104 and 500 MPN/100 mL followed by a test result the next day of LESS than 104 MPN/100 mL

A “Red” site = a test result of 500 MPN/100 mL or higher OR a test result between 104 and 500 MPN/100 mL followed by a test result the next day of 104 MPN/100 mL or GREATER
